![]() ![]() ![]() Wildberger show that this is better than what would be calculated using a trigonometric table from the Indian mathematician Madhava 3,000 years later. Next, the problem solver could have calculated the ratio 56/45, or about 1.244 and then looked up the closest entry on the table, which is line 11, which lists the ratio 1.25.įrom that line, it is then a straightforward calculation to produce an answer of 33.6 cubits. That’s what we can use this fragment for.”Ī Babylonian faced with the ziggurat word problem may have found it easy to set up: a right triangle with the long side, or hypotenuse, 56 cubits long, and one of the shorter sides 45 cubits. But when you arrange it in such a way so that you can use any known ratio of a triangle to find the other sides of a triangle, then it becomes trigonometry. “Just having a list of Pythagorean triples doesn’t help you much. “You don’t make a trigonometric table by accident,” Dr. ![]() That by itself was remarkable given that the Greek mathematician Pythagoras, for whom the triples were named, would not be born for another thousand years. This equation also represents a fundamental property of right triangles - that the square of the longest side, or hypotenuse, is the sum of the squares of the other two shorter sides.
